The asset figures and resulting ranking for the P&I/Towers Watson World 500 are derived from several sources.
The figures for the U.S.-based managers come primarily from the managers' responses to Pensions & Investments' year-end survey, which was published May 18. Towers Watson & Co., New York, conducts a separate survey to gather the data on non-U.S. managers. The data from the two surveys are then combined, with affiliated managers aggregated under the parent company.
Firms that did not respond to the P&I or Towers Watson surveys were omitted.
